Script for creation and update BPA/CPA

Hi Team,

We have requirement for creating BPA's & CPA's using SOA integration and all the required details will be coming from source system. I found scripts for creating/updating BPA on note(Doc ID 1406003.1) but that script is creating both header & line for BPA and our requirement is to create only Header. BPA lines will be managed by sperate team.

Another requirement is to update agreed amount at BPA header. I've gone through multiple blogs but couldn't workout the process for update the amount at BPA header level, we have process for updating BPA lines like unit price, expiration date and few more.
